Noosphere

Working memory of your context for AI tools.

Your thinking is scattered across threads, tools, and devices. Each conversation is a silo — what you figured out in one doesn't exist in the other. Noosphere connects them.

Think out loud on your phone, build at your desk, refine in a different tool. They all share the same context. Read more →

Connect your tools

Noosphere works with any AI tool that supports MCP. Connect as many as you want — they all share the same memory.

“Remember this decision”
“Save where we are”

The AI handles everything behind the scenes. No commands to learn.

Once your brainstorm becomes a decision, use Proto to turn it into a working prototype. Proto structures your project into a spec, plan, and tracked tasks. Subagents implement in parallel while you steer.
